(WXIA) -- It's going to be another messy weekend on metro Atlanta's highways.

The Georgia Department of Transportation encourages drivers to stay off Interstates 20 and 285 if they can.

As always, all work is weather permitting.

Scheduled construction projects include:

Bartow County* 1 northbound lane of I-75 will be closed between two miles north of Glade Road and one mile south of Allatoona Road from 9 p.m. Friday to 1 a.m. Saturday for bridge maintenance.* 1 northbound lane of I-75 will be closed between two miles north of Glade Road and one mile south of Allatoona Road from 7 a.m. Saturday to 5 p.m. Sunday for bridge maintenance.

Cobb County* 1 lane of the I-75 southbound exit ramp to I-285 west will be closed from 9 p.m. Saturday to 7 a.m. Sunday for work on the Northwest Corridor Express Lanes project.

(WXIA) -- A major project on a heavily traveled interchange is bound to cause some headaches for Atlanta-area drivers this weekend.

It's just one of several scheduled construction sessions throughout the area. All work is weather permitting.

Crews will be hard at work on the Kennedy Interchange in Cobb County much of the weekend. The Kennedy Interchange is where Interstate 75 meets Interstate 285 in the Cumberland area.

The Georgia Department of Transportation said sign installation will require multiple lane closures on the Outer Loop of I-285 just before the exit ramp to Cobb Parkway and I-75 north. Two right lanes will close at 9 a.m. Saturday; that will expand to three lanes between 11 p.m. Saturday and 8 a.m. Sunday. Outer Loop traffic will also be paced in the area beginning at around 2 a.m. Sunday.

Georgia Department of Transportation crews will be on several roads throughout metro Atlanta. As always, drivers are asked to be cautious when traveling through work zones.

Look out for workers in these areas:

Cobb County* Two southbound lanes of I-285 will be closed between Atlanta Road and South Cobb Drive from 9 p.m. Friday to 5 a.m. Monday for concrete slab replacement.* Two Inner Loop lanes and one Outer Loop lane of I-285 will be closed between Paces Ferry Road and Cobb Parkway from 9 p.m. Friday to 5 a.m. Monday for sign installation.

(WXIA) -- Last week's break from interstate roadwork was short-lived. The Georgia Department of Transportation said crews will be back on the roads this weekend.

Interstate 285, especially the portion above I-20, will be GDOT's main focus, as several projects are scheduled for that corridor.

As always, all work is weather-permitting.

Clayton/Fulton counties* 1 Outer Loop lane of I-285 will be closed at I-75 south from 7 a.m. to 5:30 p.m. Saturday and Sunday for resurfacing* 1 outside lane of I-285 will be closed at I-85 north from 9 p.m. Friday to 5 a.m. Monday for bridge repairs

Cobb County* 2 northbound and 2 southbound lanes of I-285 will be closed between South Cobb Drive and Paces Ferry Road from 9 p.m. Friday to 5 a.m. Monday for concrete slab replacement* Pacing will occur at the I-285 Kennedy Interchange with I-75 overnight Saturday
